For any open set Ω ⊂ℝ N, the space BV ( Ω) is the class of all functions u \in L^ {1}_ {loc} (\varOmega,\mathbb {R}) such that Du (the derivative of u in the distributional sense) is a finite measure. A real z ∈ℝ is an approximate limit for u at point x if
A Note on the Theory of SBV Functions
Web– In questo articolo si fornisce una dimostrazione semplice e nuova del teorema di compattezza per la classe SBV (Ω) di funzioni speciali a variazione limitata 1.-Introduction The space SBV (Ω) of special functions with bounded variation was introduced by De Giorgi and Ambrosio [6] as a natural extension of the space of piecewise smooth … WebJan 17, 2024 · The limit functional turns out to be similar to the Mumford–Shah functional with additional constraints on the jump set of admissible functions. One key ingredient in the proof is an approximation result for \(SBV^p\) functions whose … nike pro combat thermal mock
